Energy saving
zz
High energy saving was realized converting indoor unit/outdoor unit fan motors and compressor to
ALL DC, and also by optimal design of the refrigerant cycle.
Flexible installation
zz
A high installation of degree of freedom according to the construction of the ceiling.
Embedded in Ceiling
Hanging from Ceiling
Slim & compact design
zz
In the case of bottom suction type, as seen from lower rear part.
Control Box united with main unit
One-touch operating and easy-to-install
long-life filter (optional)
In addition to the slim height of 270 mm, further compactification is attained by reducing 65 mm
from the width with the flanking control box embedded inside the chassis.
Two-direction on drain piping
zz

Structural improvement is attained by making the
bottom panel two pieces, front and rear.
The internal fan casing is also manufactured
in two pieces, namely upper and lower. The
maintenance of the motor and fan can be easily
carried out by removing the rear panel and the
lower part of the casing while leaving the main
chassis installed.
Bottom panel: 2 units
Quiet operation
zz
Quiet operation at 28dB(A) is possible in quiet mode.
Economy operation
zz
The power consumption can be reduced.

Peak cut mode
Suppresses maximum capacity to perform energy-saving operation, preventing breaker tripping.
This function operates by setting a peak current value and reducing the power consumption.
* Performance drops by reducing the power consumption preferentially.
Level 1 ... S
uppresses the power consumption to almost 0% by stopping the compressor.
Level 2 ... S
uppresses the power consumption to 50% of the rated power consumption value.
Level 3 ... S
uppresses the power consumption to 75% of the rated power consumption value.
Level 4 ... S
uppresses the power consumption to the rated power consumption value (100%).
